I've tried researching, but I seriously still am not able to tell if it would or not. I previously bought a 1gig stick of ram, pc3200, 400mhz, and it didn't work. The ram that works on my computer now and came with it is a 512 stick, pc3200, 400mhz. A friend said it was becuase the stick I ordered was 32 bit, and my computer was only 16 bit. But here are my computer specs: eMachines W3503 AMD D 356 64-bit 3.3 ghz processor 512 DDR SDRAM Do you know if this ram is compatible with my computer? http://www.supergooddeal.com/ProductDetails.asp?ProductCode=D32PB1GJ&CartID=2 Thanks alot.
